Rubber Diaphragms & Seals

Rubber Diaphragms & Seals We offer a wide range of rubber seals and diaphragms to the industrial, food and chemical sectors.

Our expertise includes making composite diaphragms, for example rubber to plastic, rubber to textile or rubber to metal. We also manufacture very lightweight diaphragms for pressure-sensitive applications in the aerospace and rail industries.

Rubber seals and diaphragms can be manufactured to provide special properties such as oil, temperature, pressure, chemical or heat resistance.

Our standard product range includes a wide variety of shapes, sizes and materials, but if your application calls for a bespoke product, we can design and develop it for you, including prototypes and small or large production runs. Often bespoke products are very complex; our team of product development specialists includes polymer technologists, engineers and fabricators who work with our customers to find solutions to difficult problems, including a recent diaphragm for a sensitive application that combined rubber, metal, textile and PTFE.
